PRESSER ROLLER.

Application filed September To all 'tu/0m t may concern:

Be it known that I, JOHN L. VHEELER, a citizen of the United States, residing in the city of St. Louis and State of Missouri,

have invented new and useful Improvements in Presser Rollers, of which the following is a specification. Y This invention relates to measuring machines and is particularly applicable to fabric measuring machines which embody in their. construction a measuring roller and a co-operating presser roller lwhich holds the fabric against the face of the measuring roller. In the operation of such a machine the fabric should be drawn in a straight line between the rollers in a direction extending at right angles to the axesofthe rollers. In practice, however, the operator of such a machine pulls the cloth or fabric throughit in a more or less oblique, inclined or curved direction; the result of this is that th-e movement of the face of the measuring roller is not a true index of the amount of fabric pulled through the machine, and hence, the indicating mechanism which is actuated by the measuring roller does not truly indicate the length of the fabric measured. The general object of the present invention is to overcome this defect and provide means for insuring an accurate indication by the indi- 'cating mechanism in spite of the fact that in'operating the machine the fabric has been drawn in anoblique direction between the rollers. More specifically stated as applied to a fabric measuring machine, the invention consists in providing a novel construction for the presser roller which will cooperate with the measuring roller in suc-li a way as to affect the movement which is imparted to the measuring roller by pulling the fabric across its face and between the presser roller and the measuring roller, thereby giving the measuring roller an amount of movement that more accurately corresponds to the length of fabric pulled past the measuring-roller.

Further objects of theinvention will ap pear hereinafter.

The invention consists in the novel features, and in the general combination of parts to be particularly described hereinafter, all of which contributeto produce a simple and efficient presser roller. A preferred embodiment of my invention will be particularly described in the following spec- 20, 1920. Serial No. 411,501.

ification, while the broad scope of my invention will be pointed out in the appended claims,

In the drawing;

`Figure l is a vertical section through a fabric measuring machine of a common type, to whichl have applied my invention; and i i Y Figure 2 isv ahorizontal section taken about on the line 2h72 through the presser roller,,illustrating the preferred construction of the presser roller and also indicating the manner in which the presser rollereco-open ates to gire the desired eii'e`ct.`

'p The machine illustrated comprises aV casing or case l in the'lower portionof which there is rotatably mounted a measuring roller 2, the shaft 3 ofwhich is rotated when the measuring roller rotates, the rotation of the shaft 3 being imparted to indicating mechanism any kind (not illustrated) that indicates the length of movement of the face of the roller 2. Y(lo-operating with the measuring roller I provide a presser rollerY l which is preferably mounted upon a presser roller frame 5 including an arm 6. Associated with this frame there is provided a spring r{"thexfunction of which` is .to force the presser roller a down upon the fabric and press'the same against the upper face of the measuring roller. ln thevmachine illustrated the casing is provided with a gap 8 4through which the fabric is drawn in the direction indicated by the arrow adjacent to the line 9. With such a machine, if thefab- 'ric is pulled in a straight line between the rollers the face of the measuring roller will receive a. movement fronithe fabric which is equal to the amount of movement of the fabric, butthe operator of such a machine usually pulls the fabric through the machine in an oblique curved or inclined direction. '.lhe el'llect of this is clearly illustrated in Figure 2. in this view the position of the` operator is somewhere near the point l0. 1n pulling the fabrictlnough the machine the fabric is seized `by the opcrators hand Y near thepoint ll on the line 9 and is then pulled toward the left as viewed in Figure l. However, in ,describing this movement the operator unconsciously advances the fabric, usually not in a straight line but in a curved or oblique line about a radius the center of which lies near the operators position 10. The result of such a movement with an ordinary presser roller would be toimpart a movement to the face of the measuring roller corresponding to the maximum amount of movement given to the fabric at any point. In order to prevent this and in orderto impart a more accurate movement to the measuring roller I construct the presser roller 4 so that it consists of a plurality of roller sections 12. These roller sections are simply short rollers or spools supported on the presser roller frame 5 so that they will rotate about a common axis.y For this purpose I provide the arm 6 of the presser roller frame with an arbor 13 which is disposed parallel to the axis of the measuring roller 2. T he roller sections 12 are simply mounted in a row on this arbor so that their end faces 14 abut against each other and they are held in this close alining relation by a nut 15 mounted on the threaded end of the arbor. In order to exclude lint from the joints in the presser roller 4 which 'are fori'ned by the abutting end faces 14 of the roller sections I provide small rings 161` which may be in the form of loose slip rings fitting over the abutting ends of the rollers. Each roller section is covered by clothing or a facing composition 17 and this clothing projects outwardly beyond the rings 16, that is to say, the diameter of all the roller sections 12 is the same measured over the clothing 17 and is greater than the diameter of the slip rings.

The manner in which the presser roller of this construction co-operates'with the measuring roller to attain the desired effect Will be understood by observing the oblique or curved lines 18 and 19 which are arcs struck from the point 10 as a center.v These arcs 18 and 19 indicate in a general Way the kdirection of movement of the corresponding parts of the fabric. Evidently the fabric lying near the position'of the line 18 Will have a greater movement than that lying near the arc 19. Similarly fabric lying-adjacent tlie position of the arc 20 Will have a greater movement than the fabric lying near the intermediate arc 21. With a presser roller composed of sections 12 as illustrated,

each section tends to impart to the measuring roller a movement corresponding to the amount of movement of the fabric adjacent to that roller section; As a result of this, each roller section tendsvto produce a different amount of movement in the measuring roller from that of any other section. The

5 corresponding to the fabric which lies adjacent to the intermediate dotted line 22. This will give a movement of the measuring roller which accurately indicates the actual movement of the fabric past the roller, and hence, the measurementindicated by t-he indicating mechanism Will morel accurately indicate the actual amount of cloth or fabric measured.

vIt is understood that the embodiment of the invention described herein is only one of the many embodiments my invention may take, and I do not Wish to be limited in the practice of my invention nor in my claims, to the particular embodiment set forth. 'r p l I claim: Y

1.. In a fabric measuring machine, the combination' of a measuring roller, ,and a presser roller for pressing the fabric against the face of the measuring roller, consisting of va. plurality of independently rotatable sections of lequal diameter andsupportedv to rotate on a common axis.

2. In a fabric measuring machine, a measuring roller for imparting movement to the indicating mechanism, in combination with a presser roller composed of a plurality of independently rotatable roller scet-ions of equal diameter, and an arbor supporting the roller sections to rotate on an axis parallel with thek axis of the measuring roller, said roller sections operating to measure the average length of fabric when the 'fabric is pulled past the rollers in an oblique path.

8.' In a fabric measuring machine having a 'measuring roller, a presser roller arbor disposed substantially parallel with the axis of thelmeasuring roller, and a plurality of independently rotatable roller sections of equal diameter mounted on the arbor, said roller sections having end faces abutting against each other, rings caried on the abutting ends of the roller sections, and clothing on the roller sections projecting outwardly beyond the rings.

In testimony whereof, I have hereunto set my hand.

JOHNy L. WHEELER.
